2、予以确诊,后进行腰椎SE序列MRI扫描,就其MRI征象与BMD作对照分析。结果MRI未发现信号异常的LVOP其平均BMD高于信号异常者的平均BMD(<0.01);合并椎体疏松性骨折的LVOP其平均BMD低于未合并椎体疏松性骨折者的平均BMD(<0.01);伴发椎体终板疝的LVOP其平均BMD低度于未伴发椎体终板疝者的平均BMD(<0.05)。合并有不同类型椎体疏松性骨折的LVOP之间平均BMD的差异无显著性,单发椎体疏松性骨折与多发椎体疏松性骨折的LVOP之间平均BMD的差异亦无显著性。结论轻度的LVOP其MR
3、I信号变化不明显,合并椎体疏松性骨折者多为较严重的LVOP,LVOP伴发的椎体终板疝与腰椎BMD有关。关键词:腰椎;骨质疏松;骨密度;骨密度测定法;X线;磁共振成像中图分类号:R681.5;R445.2文献标识码:A文章编号:1002-1671(2003)03-0235-05LumbarVertebralOsteoporosis:ComparativeAnalysisBetweenMRIandDualEnergyX-rayAbsorptiometryKEQi,XUZhuo-xin,CAOHai-wei,XIACh
